The model of the Metatropic Dwarfism specifies that at birth the thorax is narrow and after the first year of age a mild kyphoscoliosis occurs. If the severity of the kyphoscoliosis is relatively mild then the thorax will continue to be narrow. If the severity of the kyphoscoliosis ....

.... features of the represented real world [3] and when reasoning about time oriented data [4] Researchers in the medical informatics field investigated temporal data modeling, temporal maintenance and temporal reasoning, to support both electronic medical records and medical expert systems [5, 6, 7, 8, 9, 10, 11, 12, 13, 14]. One indication of the significance of research on timeoriented systems in medicine is that the level and the amount of scientific works in this area motivated two different special issues of the journal ################################### [15, 16] Another indication is that research focusing on ....

Studies of time oriented applications have been performed in multiple clinical areas: cardiology [49, 50, 11, 30, 51, 47, 52, 53] oncology [45, 44, 8, 41, 35] psychiatry [26] internal medicine [54, 43, 34, 13, 46] intensive care [55, 45, 37, 56, 57] cardiac surgery [10] orthopedics [6] ....

....data, such as patient medical records, have an immediate value to a human user, such as to a physician scanning a long patient record for meaningful trends [1] 2. Temporal abstractions support recommendations by intelligent decision support systems, such as diagnostic and therapeutic systems [2]. 3. Abstractions support monitoring of plans (e.g. therapy plans) during execution of these plans (e.g. application of clinical guidelines [3] 4. Meaningful time oriented contexts enable generation of context specific abstractions, maintenance of several interpretations of the same data ....

....have been used either embodied within an application system or as the basis for a temporal reasoner in charge of providing temporal functionalities to an application system. TR has been applied in planning systems [8, 106, 92, 5] natural language understanding [120, 15, 17, 44] or expert systems [59, 31, 11, 88, 58, 94, 95], to cite few of them. A set of ontological and representational issues has to be considered in defining a TR system. The rest of this article is devoted to presenting and analysing them. For each I discuss the advantages and problems of the different choices that one can make 1 . Therefore, in ....
